The cotZ gene was amplified from the genome of B. subtilis and the anti-GFP nanobody was amplified from an expression plasmid. The HA tag and the alpha helical linker were introduced by primer extensions. Both PCR fragments were assembled by Gibson cloning into pSB1C3. The fusion construct can released by XbaI and PstI and cloned alongside with an appropriate promoter into an integration vector for B. subtilis by 3A assembly.

The cotZ gene was amplified from the genome of B. subtilis and the anti-GFP nanobody was amplified from an expression plasmid. The HA tag and the alpha helical linker were introduced by primer extensions. Both PCR fragments were assembled by Gibson cloning into pSB1C3.
